Got Google Pay working in the Sandbox. Now trying Masterpass.
Looks very pretty and responsive, but when it comes back to the payment form just gives
SERVICE_UNAVAILABLE - The endpoint is currently unavailable
Any reasons why that might be the case or why it would come back with that message ??
I’m using a VPN to the USA, I’m also not using https currently.
But Google Pay and the standard CC form is working fine under the same conditions.
The message is returned on entering the cardNonceReceived function.
